A TankerRay is another word for an orgasm. Not your normal Big-O, but a fake. When a guy doesn't pleasure a girl enough to make her orgasm, she will usually fake it, or use a "TankerRay", so make the man feel like he is actually good in bed, when all the woman know he's not. Or, when you would like to prank someone, by moaning in a populated area, for example a mall or a class room, they will "TankerRay" to get odd looks from peers. Usually when a girl has intercourse with a really short guy, or a guy who likes to straighten his pubic hair instead of shaving it, the female does a TankerRay.

"Hey, Rachel, Dakota was so terrible in bed after five minutes I had to TankerRay!"
